Emon Energy Meter

The EMON energy meter is specifically designed for energy measurement in electric traction vehicles. It can measure both DC and AC signals of any existing traction supply system (1.5kV DC, 3kV DC, 15kV/16.7 Hz, 25kV/50Hz). It is also suitable for multi-system locomotives using more than one electrification system.

The energy meter measures both consumed and generated active and reactive energy, active and reactive power and instantaneous values of voltages and currents. At 1 minute intervals it records load profiles and monitors the minima and maxima of the measured values.

The energy meter can transmit measured data wirelessly over GSM/GSM-R/UMTS and WiFi networks. An integrated GPS receiver adds location information to the load profiles and is used for time synchronization.

EMON is a certified energy meter according to the latest EN 50463-2:2017 standard. It meets the requirements of accuracy class 0.5R. The energy meter can be supplied with a calibration certificate enabling its use for billing purposes.
